摘要

In this paper we investigate a free corrective heat and mass transfer flow of an incompressible viscous fluid through a heat generated saturated porous medium enclosed in a circular duct using Brinkman model. The lower half portion of the duct is insulated while the upper half is maintained at constant temperature and concentration. The Galerkin finite element method with six nodded triangular elements is adopted to obtain the iterative solutions for the stream function, temperature and concentration by the coupled non linear equations. The flow being symmetric, the expressions for velocity, temperature and concentration are obtained in typical quadrant of circular duct. Their behavior is discussed for variation in governing parameters Ra, D~(-1), Sc and a. The local rate of heat transfer and mass transfer are also investigated computationally.
